Unfortunately, no, the iRig HD 2 is not Android compatible.
Check out the iRig UA or iRig 2 for Android compatible iRig devices.
https://www.ikmultimedia.com/irigua/https://www.ikmultimedia.com/irig2/Note* The iRig UA includes a built in DSP chip. This acts as the 'brain' when using (The free) AmpliTube UA which allows for a universal experience on the Android platform. When using other app, the iRig UA will act as any other audio interface. To be compatible with this device you will only need Android 4.2 or later and a USB Host compatible Android device.
Hope this helps!
